Dollar Sign Expansion with parameters
It is also possible to create variables with parameters and then call them via a DSE
specifying the parameter's value, thus allowing extended flexibility and reusability
of variables.
The way we create a variable with parameters is as follows:
1. Open the Variable Overview… window (Ctrl + Alt + V) and create a new
variable. Name it eDeparturesPerformed_VarUnit .
2. The variable definition will be:
Sum([# Departures Performed]) / $1
3. In the Comment field, enter Variable to calculate the number of
departures performed with variable divisor .
4. Close the Variable Overview… window by clicking on OK.

To use the above variable in an expression, start by creating a new chart in the
form of a straight table with Carrier Group as the dimension and the following
three expressions:
1. The first expression, labeled # of Flights , will be:
$(eDeparturesPerformed_VarUnit(1))
2. The second expression, labeled # of Flights (thousands) , will be:
$(eDeparturesPerformed_VarUnit(1000))
3. The third expression, labeled # of Flights (millions) , will be:
$(eDeparturesPerformed_VarUnit(1000000))
